I got spankings from my mom on my bare bottom for as long as I can remember. Interestingly, they never hurt at all and as a little girl I would cry aloud so that mom would think they hurt even though they didn't. I figured that if I didn't cry she would spank me harder.
As I started going through puberty I discovered one evening that I was enjoying these painless spankings and my first masturbation session revolved around a spanking she gave me before bed. My mom hates cursing and I would deliberately let a curse slip out of my mouth knowing it would lead to a spanking. After the spanking I would masturbate in my room.
Then it happened, dad suggested to mom that at thirteen I was getting too old to be spanked. Mom continued to spank me but only when dad had to work overtime. I was enjoying these ordeals more and more. At the age of sixteen mom asked me if I was acting up on purpose in order to get a spanking. I admitted that I was. Mom then told me to just ask her in the future if I wanted a spanking and she would give me one. She even asked me if I touched myself after the spanking and I admitted that I did.
I'm now nineteen and mom continues to spank me when I ask for one. I asked her once to spank me harder and she did. It was just right. My best masturbation times are right after I get a spanking. When I come out of my room mom always asks me if I now feel better. I always do. I should also tell you that mom has never done anything sexual to me either before, during, or after the spanking. Not that I would mind if she did.
